Was there ever an answer to this? I just lost several thousand images in what appeared to be a successful transfer. But now, the images are not possible to locate with standard tools.
Only a reliable backup of images can guarantee restoration.
Recovery software is doubtful. (Recuva Recuva - Restore deleted files, even if you've emptied the Recycle bin! - Piriform )
Images can be recovered from the Lightroom Preview folder, but their pixel resolution depends very much on how the previews were created by Lightroom- Jeffrey Friedl's Blog » Jeffrey’s “Extract Cached Image Previews” Lightroom Plugin
This is a very difficult way to learn the lesson that you MUST make regular and automated backups of your photos and catalog file, to a different physical disk than the originals.
And ... don't move large amounts of files using LR from now on ... instead, use the method explained in "Part 2 — Updating Folder Location" in this document: Adobe Lightroom - Find moved or missing files and folders
Hi all, interesting to see this topic resurrected. I totally lost the data there, was a major lesson.
Since then, I've 1) Been transferring photos in Explorer and updating the folder location like dj_paige said, and 2) maintaining 1:1 previews for important images.
1:1 previews give me assurance that I'll have something even if I deleted a master folder, and between that and better file transfer practice I haven't run into any issues since.
Still think about the stills and video that I lost though. The memories don't disappear so easy, ha.

No- it does NOT! So be warned-
1:1 previews are transitory, they only exist in a temporary cache (the .LRDATA folder). They are NOT image files, and Lightroom can automatically delete 1:1 previews after a time, depending on the settings in the Preferences. So emergency recovering of images from previews may NOT give you back the full file resolution. (Some who have recovered from Previews have found they only have thumbnail images!)
So I repeat what Paige says-
you MUST make regular and automated backups of your photos and catalog file, to a different physical disk than the originals.
"photos" means- you original "out-of-camera" files -the ONLY reliable files for restoration of 'lost' images from a backup.
